Geo Oceans has set a new standard in survey efficiency and data quality by performing a range of real-time data analysis and processing tasks in the field. Our Mini-ROV systems and towed cameras (drop camera) combine with our GO Visions™ software, allowing for the collection of larger quantities of higher quality processed data. This allows us to create fine-scale habitat maps across large spatial areas, far more accurately and efficiently than previously possible. The data can also be collated with other marine habitat and bathymetry survey data to model to map the distribution of the marine habitats. The maps can be used to quantify the spatial area of the marine habitats and to monitor changes over time.


Our HD stereo video system mounted on a Mini-ROV records fish species for identification, enumeration and measurement.

Our experienced team use specialised fish survey software to count individuals and measure size to millimetre accuracy. The Mini-ROV system comes with the additional advantage of being very quiet, reducing the disruption of fish behaviour that can occur with divers. The GO Visions™ software provides an accurate measure of the size of the area surveyed.

  • Real-time statistical data processing to check the data meets requirements
  • Production of fine-scale habitat maps (in real-time) to assist site selection
  • Reduced variance between replicates
  • Lower cost per sample means more replicates can be collected
  • High spatial accuracy improves repeatability
  • Operable in extreme conditions so exposed sites are not excluded
  • Stereo images allow accurate size measurements


Geo Oceans offers diverless Mini-ROV and subsea survey technologies for invasive marine species (IMS) inspections. High definition video, still images and inspection data are captured and viewed in real-time using towed cameras, ROVs and specialised software. The equipment can be transported on planes for quick mobilisation with small teams, anywhere at any time.

For IMS surveys we work closely with specialist biosecurity consultants to deliver the full range of biosecurity services and capabilities, including approved biofouling and IMS inspectors. This combination of biosecurity expertise coupled with our innovative diverless Mini-ROV and subsea Inspection technology provides the industry with an efficient and cutting-edge approach to meeting their biosecurity obligations.

The combination of biosecurity survey capabilities with diverless and Mini-ROV technologies provides industry with another effective approach to meet biosecurity marine area and marine infrastructure survey obligations. These capabilities may serve as an early warning system, identifying the introduction and spread of an IMS or be used following the discovery of an IMS, fulfilling subsequent IMS control and management requirements.

  • Industry leading IMS specialists ensuring compliance
  • Lower cost solution to marine biosecurity
  • Operable in extreme conditions so exposed sites are not excluded
  • Stereo images allow accurate size measurements
  • HD still imagery and video footage with real time data transfer


Benthic Marine Habitat Monitoring Survey

Big Bank Shoal in the Timor Sea is 560 km offshore from Darwin. Geo Oceans chartered a vessel contractor and mobilised a two person team and GO Visions towed camera (drop camera system) to site to complete a marine benthic habitat survey, in support of the client’s environmental management objectives for the Buffalo Oil Field development. The team captured geo-referenced HD video footage, DSLR still images of the seafloor and GO Visions™ marine habitat GIS data across benthic transects.

2019 Great Barrier Reef Towed Camera Survey

Geo Oceans’ marine scientists mobilised a towed camera (drop camera) and Mini ROV system with USBL spatial positioning to the north east coast of Australia to capture geo-referenced still images and HD video over several coral patches. The images were analysed for biota (e.g. coral, seagrass macroalgae) percent cover and substrate profile and type using the GO Visions™ software. The data were displayed in GIS software in real-time as point data overlaid on multibeam sonar data, and the outputs were used to guide site selection and survey design during the campaign.

Dredging Benthic Marine Habitat Monitoring Program

This seagrass monitoring program supported the environmental management of maintenance dredging operations in the approach channel to Cullen Bay Marina in Darwin. Geo Oceans developed the seagrass monitoring program to meet regulatory requirements and completed surveys prior to (baseline) and immediately after the dredging campaign. Geo-referenced HD video footage, DSLR still images and GO Visions™ benthic marine habitat GIS data were collected from reference site transects.

Brunei ROV Coral Survey

Geo Oceans completed an ROV coral monitoring survey in Brunei for Shell. Mini ROV survey equipment combined with GO Visions™ marine habitat survey technology was used to capture spatially accurate HD video, still images and marine habitat data. The multidisciplinary field team included an experienced ROV Supervisor and a marine scientist trained in habitat surveys and ROV operations. Post-survey, the GIS coral data were analysed, mapped and included in a technical report that supported the client’s environmental management of their operations in the region.

Towed Camera Coral Survey - Asia

Geo Oceans completed a coral survey in the offshore Champion Field, Borneo Asia, to assess coral condition prior to seismic investigations. The GO Visions™ towed camera (drop camera) system collected geo- referenced HD video, still imagery and data of coral habitats. The intensive survey acquired 20,567 points of qualitative habitat data and 7612 still images across 44 transects over 4 days.

Decommissioning Program Bathymetric and Habitat Mapping

Geo Oceans was engaged to perform a bathymetric and habitat mapping survey prior to the arrival of construction vessels to the Airlie Island site, offshore of Onslow in Western Australia. Proposed anchoring locations and safe approach channels were accurately mapped and surveyed for sensitive marine habitats, raised features and bathymetry using towed camera and multibeam echo sounder systems.
